I think you don't understand the core argument re the SSO Tax, which is that security is a positive sum good, which is why it should not be the feature used for price discrimination.
Not all products have other good features to use for price discrimination, so I have some sympathy for vendors here, but I think it often indicates laziness in thinking about what they can use to do the necessary price discrimination.
